I'm 6'4" with a long torso and average length arms. My bike fitter told me I should get a custom bike because most frame manufacturers won't have enough top tube length. I started pricing custom frames and almost died of sticker shock.
When I crashed out my existing bike, I got a Fezzari with a 61cm frame with a 130mm stem. They do customize the fit for you and give you a free bike fitting. It's as close to a customized bike as I can afford...
